i To all whom it may concern:

Beit known that I, HAROLD W. SHON- NARD, resic ing at Upper Montclair, in the county on see); and State ofNew Jersey,

a citizen of the United States, have invented or discoveredcertain new and useful Improvements in separable-Torpedo Construction,*Case A, of which improvements the following is a specification.

In the manufacture of automobile torpedoes it is the usual practice to construct the casing or shell of a plurality of sections joined together in transverse planes in such aYmahner that they may be readily sepa- .15

rated for Whatever purpose desired. "When,

through the general plane of such a joint,

a] fluid conduit passes Within the torpedo \from one shell section to another, it becomes necessary to divide theconduit into two parts, one being carried by each shell sec- 1 tion. Heretofore ordinary union couplings havebeen used for connectlng these condu t I pling collar by the toof,

darts. To make or break the coupling, it as been necessary to insert pipe-wrench or other suitable tool through an opening in the shell, and, havin engaged the couoscillate the tool until the collar has been sufficiently rotated in one direction or the other. Because of the limitations placed upon the size of the shell opening for the tool (the shell being unduly weakened by a large opening), the permissible range of oscillation of the tool has been ver'ysmall, so small in fact that a very c0nsiderable'period of time is required to make or break the coupling.

In view of the foregoing considerations,

it is the object of my invention to provide an automobile torpedo wherein the conduit coupling or couplings at a point of separation of shell parts may be quickly and easily made or broken.

In the. accompanying sheet of drawings,

. whichfor'm part of my specification, I have illustrated the preferred embodiment of my 1 invention. Figure 1 is a transverse section of an automobile torpedo taken on the line y y I I, Fig. 2; Fig. 2 a longitudinal sectional view of a portion of the torpedo, the plane of view being taken on the broken line II-11, Fig. 1; and Fig. 3 a detached sectional view to enlarged scale taken on the line III'III, Fig. 1.

pedo, provided only that at such joint a fluid conduit passes from one to the other of the adjoining shell sections, it is particularly applicable to the joint between the turbine compartment and thecompartment immediately fore thereof, and is 'so illustrated in the drawings. In the usual construction of torpedoes the last mentioned compartment contains the motive fluid generator and the various essential conduits and valves for conducting and regulating the flow of var1- ous fluids (usually air, water-and alcohol) from their sources of supply to such generator. 1

Referring to the illustrative "embodiment of my invention, portions of fore and aft shell sections are indicated at 1 and 2, respectively, their adjoining ends being provided with collars 3' and 4, adaptedto be detachably connected to each other by bolts 5, and acting also as reinforcing flanges. The aft section 2 is provided with a bulkhead 6 which separates the interior of the torpedo into a turbine compartment in which a turbine 7 is placed, and an open-to-thesea compartment in which is placed the motive fiuid generatorS and the various conduits leading thereto.

reasons it is desirable to attach the motive fluid generator to the turbine-containing sec tion of the torpedo. As shown herein it is attached to the bulkhead 6,*the outlet c'on'- duit 9 extending from the generator through the bulkhead and terminating with a turbine nozzle 10.

In making or breaking the connection between the fore and aft shell sections 1 and 2, it is necessary, when the generator is carried by the section 2 as just explained, to make or break connections in all the con duits leading to the heater. These conduits, as shown herein, arethe main air supply conduit 11, and the smaller conduits 12, 13, and 14 which may correspond in function to the conduits 26, 36 and 37 fully shown and described in my U. S. Letters Patent No; 1,207,333. It is through the several conduits leading to and from the heater that the (lpeater is preferably attached to the bulk- The connections which I provide for these conduits are characterized by the fact that the conduit coupling members are attached to each other by a rotatable member pro- Vided W th a head which is engageable for continuous 'yvrench or other suitable tool inserted throughiasuitably provided holei in the Y shellse'ction 1; a 7
